Answer:
Types of Potential Energy
Elastic Potential Energy. Anything that can act like a spring or a rubber band can have elastic potential energy. ...
Gravitational Potential Energy. There is a constant attractive force between the Earth and everything surrounding it, due to gravity. ...
Chemical Potential Energy.
(IF THIS HELPED CAN YOU PLEASE GIVE ME A BRAINYLEST?)
It would be D. The force that holds together the elements in a compound.

Explanation:
Answer:
.4998 atm ( rounded to .5 atm ) <===== not one of the answers listed
Explanation:
The partial pressure exerted by O2 is equal to the fraction that is O2 times the pressure
1.5 / ( 1.5 + 1.2 + .301 ) * 1 atm = .4998 atm
<u>( 1) Are you sure it is ONE atm pressure in the container?</u>
<u>(2) IS the first answer supposed to be 5 x 10^-1 atm perhaps?</u>
Answer:
ΔH = + 116 kJ
Explanation:
The equation for the reaction is given as;
HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l) ΔH = - 58 kJ
If we multiply the above equation all through with (2); we have:
2 × (HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l) ΔH = - 58 kJ)
2HCl(aq) + 2NaOH(aq) → 2NaCl(aq) + 2H2O(l) ΔH = - 116 kJ
If we tend to reverse the above equation; we have
2NaCl(aq) + 2H2O(l) → 2HCl(aq) + 2NaOH(aq) ΔH = + 116 kJ
∴ The reaction is said to be endothermin , as 116 kJ are absorbed.
